If the fuse keeps poping (burning out) than you have a short that needs to be fixed. The fuses are there so if a wire does short (grounds out), the fuse will blow instead of the wiring heating up and melting or catching on fire. If the fuse pops as soon as you turn the key on, what you need to do is have plenty of fuses, best thing to do is disconnect one item at a time -- ie unhook the wires going to the radio(unhook the wires straight from the fuse block, not at the back of the radio), put a fuse in and see if it pops, if it does than its not the radio, unhook the wires for the door locks(straight from the fuse block again), put a fuse in, see if it pops, etc. Once you find out which device is causing the problem than you might be able to trace the wiring down and find where it is burned or where its somehow been moved and is grounding out. If you cant find it by using a visual inspecting (eyeballing it), than you will need a test light to find the short, but that becomes a whole other answer for using a test light to find a short.

1987 Pontiac Firebird and the dash lights do not work you did replace the dimmer switch and the headlight switch that did not work When you turn on the headlights the radio light goes out?

The instrument cluster lights have their own fuse. It's a 5 amp at the bottom center of the fuse block. When the lights are on, the radio draws lamp power from the instrument cluster. This allows you to dim the brightness of the radio display with the other internal lamps.

A radio fuse might keep blowing if the radio itself needs an inline fuse in a 1997 Crown Victoria. It is possible that the radio and interior lights are not grounded properly. Installing an inline fuse between the radio and the fuse box may solve the problem of the fuse blowing.

Dash lights and tailights on many cars are fused together; someone tapped into this circuit for power to the radio and has caused a short. Unhook the power lead for the radio and splice it into its own circuit and the problem will go away. I hope this helps you. Mark
